Abstract
A direct-type LED backlight module includes a supporting base having a supporting face, an LED mounted on the supporting face of the supporting base, and a dome-like light guiding cover positioned on the supporting face of the supporting base and covering the LED. The light guiding cover defines a plurality of through holes for permitting light emitted from the LED to pass through light guiding cover. The through holes are spaced from each other and arranged in a number of imaginary concentric circles relative to a center of the light guiding cover. An inner face of the light guiding cover facing the LED is coated with a reflective film. A semispherical light reflecting portion protrudes downwardly from an inner face of a top portion of the light guiding cover towards the LED.
Claims15
A direct-type LED (light emitting diode) backlight module comprising:
- a supporting base having a supporting face;
- an LED mounted on the supporting face of the supporting base;
- and
- a dome-shaped light guiding cover positioned on the supporting face of the supporting base and covering the LED, wherein the light guiding cover defines a plurality of through holes for permitting light emitted from the LED to pass through the light guiding cover, the through holes are spaced from each other and arranged in a number of imaginary concentric circles relative to a center of the light guiding cover.
An LED module comprising:
- a supporting base having a supporting face;
- an LED mounted on the supporting face;
- and
- a light guiding cover mounted on the supporting face and covering the LED, the light guiding cover having a dome-shaped configuration with a circular bottom end attached to the supporting base, a light reflective and semispherical protrusion extending downwardly from a central top of the light guiding cover toward the LED, an inner face of the light guiding cover facing the LED being light reflective, and a plurality of through holes being defined in the light guiding cover for radiation of light generated by the LED out of the light guiding cover.
